Metal window construction.



' to permit. the necessary relative movement against' the inner end o't the plunger and hott-ein wall of the guide-groove a series of Ii un) resaca? pivot-.ed at 2O to one wall ot the sash-bar, one arm ot said lever engaging a notch 12 in the plungen and the other arin having a pinch-handle 21 projecting through an opening 2Q. in the sash-bar and coperatingwith a stationary pinch-handle Figs. 5, 6, T and 8 illustrate some modiications or" the device above described as well as sonic additional features of improvement that nia-y be employed. In these views 24 designates the inner adjusting strip carried by the having its outer edges bent or lipped in wardlys as at 2l (Fig. (l), and these inturned lips engage cooperating inwardly projecting inclined lips or flanges 25 termed on a strip that is retained in the guidegroove. The ineinbers 2st and 25 are preterably both otl elastic sheet-metal, so that 'formed integral with the transverse `member l ot the channel.strip 9 are a series ol' suitably j spaced cam inclines ila that are adapted .tor coperation with a corresponding se 1ies of similarly inclined cam members 11"L forn'ied in or on a strip A11 secured to the inner trans verse n'ieinber the stile 1.

it will be observed that the cooperating inclines and 11 are so disposed that a doi'vnward movement ot'. 'the strip 9 relatiif'c-ly to 'the sash7 or an upward movement ot the sash relatively to the strip -forces the latter outwardly .into snug engagement with the bottoni Vall ot the groove. and thus adjusts the sash to a snug lit in the 'window opening. rllhe inclination ot' the niernberslln and 11"L is et such a degree as will secure a sullicient lifting effect upon the channel strip 9 when the sash is raised sash-stile7 which strip is shown as to overcome the friction ot the lips 10 of the engaging members 24faiid Q5 are both the channel strip upon the bottom of the. resilient and cooperate, under outward A oove. while at the same time perthrust oit the adjusting strip, to not only. rnittingl a sutlicient wedging action between malte a tight tit between the parts 24 and 25a, but also to torce tlie';;sides of the sashstile laterally into snug Vengageinent with the guide-strips 5 and il ot the guide-groove. In this niodilicat-ion l have also shown, in place ot the cani inclines 9 ot Fig. 1, rollers QG riding on the incliiies 11 carried by the sash; this construction making a more sensitive device by reason ot the anti-friction character ot the engaging parts which tend to torce the adjusting strip outwardly'into the guide-groove- In this construction have also shown a simple con'iprcssion spring 27 located between the bottom of the cani member il and an inwardly turned portion 2S ot the adjusting strip tor the purpose o Vforcing the latter downwardly relatively to the sash. 'llie release ot' the adjusting strip may be ell'ectcd by any suitable or convenient lifting means applied thereto7 the means herein shown consisting otl a slide Ztl mounted in a slideuvay il() in the lower sash-bar, said slide having an inclined nose 31 underlying a roller 32 carried by the adjusting strip, said inclined nose being 'forced outwardly beneath said roller so as to raise said strip by an elbow lever pivi-ited at 34- to the sash-bar and having one arm thereof engaging a shoulder 3G on the slide, the

the channel strip and the sas.l to etlect the descrilied snug engagement ot' the adjusting channel-strip with the bottom Wall the groove. Various means, including gravity" alone, niay be employed Within the purview ot my invention to effect this relative movenient of the adjusting strip and sash; the means shown in Figs. 1 and 3 consisting ot the lolljoiviiig. il pl ringer 12 is slidably mounted in keeper 13 and on a pin 14 in one or both ot the lower corners ot the sash, said keeper being secured to the inner side et one et the side walls ot the sash 1' and projecting inwardly through an opening 15 in the adjacent Ifle wall of the adjusting strip il, said opcning'lgieing ot sntlicient size between the adjusting strip and the sash stile to effect,- -the described adjustment of the sash in its guide-groove. The inner transverse wall ot the adjusting strip S) is also vertically slotted, as shown at 15a to permit longitudinal play ot said adjusting' strip over the plunger 12. spring 1G acts normally7 tends to 'torce the latter outwardly. 'lhe plunger has a depending lug 17 having an inclined lower edge that engages a corresjliondingly inclined projection 9b ot the other arin being provided with a `pinchstrip il? so that the outer thrust ot the pliinhandle 37 projecting through an opening 38 in the sash-bar and cooperating with a stationary.pinch-handle 3f). The sash is supported by any suitable or desired form of sash balance` the lower end of the tape or cord ot which is indicated at as secured to the upper transverse bar of the sash. In these views, l have shown a construction of sash wherein one side wall 4-0 ot the stile is hinged along its inner edge to the sash so as to be capable ot transverse yielding under th'e lateral thrust et the adjustment strip 24 or any other device that may be employed g r operates thereby t0 'torce 'the Strip 9 do\vn \i'ardl y relatively to the sash; and this action takes place atany adjusted position of the sash. -The plunger lfniay also be made' to serve as a supporting incans and positive lock for the sash by forming in the 18 into which the end ot the plunger may project. The plungen may be retracted in order to release the wedging engagement ot the sash and adjusting strip by means of an angle lever 19 suitably lspaced holes plane as the sill on which it rests.

for the same purpose. A convenient manner and means of liingingl said side wall at an end thereof is illustrated more particularly in the sectional detail view, F ig. 8, wherein it will be seen that the inner edge of the wall is provided with an inturned hinge member 1.0 that interlits with a correspondingly formed hinge member ll secured by rivets 4Q to the wall 43 of the bar Q or 3. One or more similar intermediate hinges may be employed connecting the wall 40 to the vertical transverse member of the stile. In this construction, the riveted miter joint at the corner of the sash will be applied only at the side opposite that formed by the hinged wall 4:0, in order to permit the freedom of movement otl the latter.

The hinged member last described may be other than a side wall of a stile or bar and may be a hinged attachment to the sash guide applied wherever a yieldable member oi or coperating with the sash is desired for the genera-l purposes described.

In Fig. 9 I have illustrated a device in the nature of an adjusting and cushioning strip for the sash, which, may be said to have two particular functions. In the first place, by being made ot different. angular forms in cross-section, it is designed to adapt a sash having a square or transversely horizontal lower edge to a sill of any angle ot' inclination; and in fact, it may compen-l sate for any angular variance between the lower edge of the sash and the sill. In the second place, 'by being made in various heights, it may compensate for slight diiierences in the proper height ot the sash relatively to the opening closed thereby. As

shown, it comprises the same angular relation 'to a vert-ical or horizontal plane as that occupied by the lower edge of the sash, and having a lower surface occupying the. same angular relation to a vertical or horizontal In the simple form herein shown., the member is made of a metal strip suitably bent to` form the, upper surface 44: conforming to the lower ede: of the sash, the lower inclined surface 45 conforming to the inclination of the sill Lt6; and connectiug'walls 47 and 48. The strip also preferably employs one or more projections -f on its .upper surface engaging recesses or sockets .50 in the lower edge ot' the sash prevent lateral displacement et the strip; and where a cushioning eliect is desired the entire strip is surrounded by an envelop ot yielding material, such as rubber, telt, leather, or the like, indicated at 5l. rlhe strip may be conveniently securedA in place byscrews 52 that may becntered through openings 53 in the lower side of the strip and its envelop and passed through registering apertures in the projection and socket and secured by nuts 54. It

will be evident that maling this strip of varying heights, as well as of varying degrecs of inclination of its upper and lower surfaces, it will not only compensate for variations in the vertical dimension of the sash, but will also compensate for any angular variations between the lower edge of the sash and the sill. Such an adjusting strip might be applied-to any part of the sash where it could be usefully employed.

While I have shown the improvements of my invention as applied to one Side only of a sash, it will be evident that they may be applied to both sides, if desired.

.It will be evident to those skilled in the art that the various features hereinabove described are capable of modification and variation in respect to details without any substantial change in character or function, and hence it should be understood that the invention is not limited to the particular constructions disclosed except to the extent indicated in specific claims.
